Videonystagmographic analysis of efficacy of Epleys maneuver alone and Epleys maneuver with Brandt-Daroff exercises in treatment of posterior canal benign paroxysmal positional vertigo

Benign Paroxysmal Positional Vertigo ( BPPV ) is the most common cause of peripheral vertigo. It is a peripheral vestibular disorder which involves any of the three semicircular canals , most commonly the posterior canal in 60 to 90 % cases and the most common cause being idiopathic. The presenting symptom of BPPV is classically a short duration vertigo, triggered by movements of the head in relation to gravity, often lying down or turning over in bed, tilting the head back or bending forward.

This study aims at comparing the efficacy of Epley’s maneuver alone and Epley’s maneuver with Brandt-Daroff exercises in treating posterior canal benign paroxysmal positional vertigo. All patients with complaints of vertigo will undergo detailed history and clinical examination, and those diagnosed as posterior canal BPPV on Dix Hallpike maneuver will be included in the study, their symptoms scored using the UCLA dizziness questionnaire and the nystagmus assessed using videonystagmography, after obtaining their consent. The patients will be randomised into two groups. Group A will receive Epley’s maneuver while B will receive Epley’s maneuver followed by Brandt-Daroff exercises.

The patients will be followed up weekly for 2 weeks and after a month. The treatment efficacy will be assessed by subjective resolution of symptomatic vertigo, a decrease in the UCLA score, and absence of nystagmus on Dix Hallpike maneuver and videonystagmography, thereby finding out which group has less recurrence.
